The aFe Silver Bullet throttle body spacer set is precision machined from 6061-T6 billet aluminum for the Nissan/Infiniti VQ37VHR 3.7L V6. Its serrated/helix bore creates turbulence in the intake charge to improve throttle response and low-end torque while reducing the whistle of helix-only designs. Because the VQ uses a dual throttle body layout, the kit includes two spacers, and both install on the factory mounting locations for a direct-fit setup.
